Description

Technical Field

[0001] The invention relates to the technical field of kilns, and in particular to a kiln car guide rail structure with seamless and efficient transition and a kiln. Background Art

[0002] The kiln car is a transport equipment that carries the blanks or tiles for baking in the tunnel kiln (or intermittent kiln). It is a key component of the tunnel kiln. The structure of the kiln car is mainly composed of a frame, a wheel set and a skirt. When working, the kiln car needs to bear the gravity of the items on the car (including lining bricks and material stacks) and the thrust of the car pusher.

[0003] When the kiln car passes the return line, it needs to be driven by the translation vehicle to move horizontally to the kiln mouth of the tunnel kiln so that the kiln car can align with the guide rail; when the kiln car enters the tunnel kiln along the guide rail, it needs to be driven by the translation vehicle again from the kiln tail of the tunnel kiln to the return line and align with the guide rail. The products on the kiln car will be unloaded on the return line, and there is generally a certain gap between the guide rail in the tunnel kiln and the guide rail on the translation vehicle, such as 5mm. When the wheels of the kiln car pass through the gap, the kiln car will shake, causing the kiln furniture on the kiln car to be displaced or damaged, which will shorten the service life of the kiln furniture and affect the transportation safety of the products on the kiln car. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a kiln car guide rail structure and a kiln furnace with seamless and efficient transition, which can ensure that the kiln car transitions smoothly and efficiently without vibration when passing through the gap between the guide rails, thereby improving the service life of the kiln furniture and the kiln car, and at the same time, ensuring the safe transportation of the products on the kiln car.

[0005] The first embodiment of the present invention provides a kiln car guide rail structure with seamless and efficient transition, which includes:

[0006] a first guide rail assembly;

[0007] A second guide rail assembly, which and the first guide rail assembly both extend along a first direction and are arranged opposite to and spaced apart from each other in the first direction;

[0008] A transition rail assembly is provided between the first rail assembly and the second rail assembly, the transition rail assembly is provided with a force-bearing member, the force-bearing member and the transition rail assembly are spaced apart in a second direction, the transition rail assembly is configured to rotate forward and overlap the second rail assembly when the force-bearing member is subjected to an external force, so that the first rail assembly, the transition rail assembly and the second rail assembly are connected in sequence to form a rail assembly, and is configured to rotate in the reverse direction by itself after the external force is removed;

[0009] The kiln car body has wheels that can roll along the extension direction of the guide rail assembly.

[0011] When the kiln car body is completely transferred to the second guide rail assembly, the external force applied by the force-applying member to the force-receiving member disappears, and the transition guide rail assembly automatically rotates in the opposite direction, so that the second guide rail assembly is separated from the transition guide rail assembly, making it easier for the second guide rail assembly to drive the kiln car body to move relative to the first guide rail assembly along the second direction.

[0017] In some embodiments of the present invention, the force applying member is provided with a guide surface, and the guide surface can contact the pressure wheel and drive the pressure wheel to drive the transition guide rail to rotate in a positive direction.

[0018] In some embodiments of the present invention, each of the wheels is provided with a force-applying member on one side in the second direction, and the force-applying member is provided with guide surfaces at both opposite ends in the first direction.

DETAILED DESCRIPTION

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Reference below Figures 1 to 7 A kiln car guide rail structure and a kiln with seamless and efficient transition provided according to an embodiment of the present invention are described.

[0035] like Figures 1 to 7 As shown, the kiln car guide rail structure with seamless and efficient transition according to the first aspect of the embodiment of the present invention can be applied to a tunnel kiln to complete the task of transporting product 320 by the kiln car.

[0036] The kiln car guide rail structure with seamless and efficient transition includes a first guide rail assembly, a second guide rail assembly, a transition guide rail assembly and a kiln car body 300. The kiln car guide rail structure has a first direction, a second direction and an up-down direction. The first direction is not only perpendicular to the second direction, but also perpendicular to the up-down direction. The second direction is perpendicular to the up-down direction. In this embodiment, it is assumed that the first direction is the left-right direction and the second direction is the front-back direction.

[0037] The length of the first guide rail assembly extends along the first direction, and the first guide rail assembly includes at least two first guide rails 100 arranged side by side, and all the first guide rails 100 are arranged at a certain interval along the second direction. The length of the second guide rail assembly extends along the first direction, and the second guide rail assembly includes at least two second guide rails 200 arranged side by side, and all the second guide rails 200 are arranged at a certain interval along the second direction. Moreover, the first guide rail assembly and the second guide rail assembly are arranged opposite to each other in the first direction and are arranged at a certain interval.

[0038] It is understandable that the first guide rail 100 and the second guide rail 200 are identical in number, and a gap 600 is formed between the first guide rail 100 and the second guide rail 200. The gap 600 between the first guide rail 100 and the second guide rail 200 can be set according to actual conditions, and the number of the first guide rail 100 and the second guide rail 200 can be selected according to actual needs, and is not specifically limited here. In this embodiment, two first guide rails 100 and two second guide rails 200 are provided. The first guide rail 100 and the second guide rail 200 can be H-shaped guide rails or T-shaped guide rails.

[0039] The first guide rail 100 is arranged inside the tunnel kiln and installed on the ground. The first guide rail 100 extends from the kiln head to the kiln tail of the tunnel kiln, so that the kiln car body 300 can move from the kiln head to the kiln tail along the first guide rail 100. In addition, the first guide rail 100 can also be arranged outside the tunnel kiln and installed on the ground as a return line of the tunnel kiln, so that the kiln car body 300 can return from the kiln tail to the kiln head via the return line. The second guide rail 200 is arranged outside the tunnel kiln and installed on the translation vehicle 700 of the tunnel kiln. The second guide rail 200 can move with the translation vehicle 700 to translate the kiln car body 300 from the kiln tail to the return line, or from the return line to the kiln head.

[0040] The transition rail assembly is disposed between the first rail assembly and the second rail assembly. The transition rail assembly includes at least two transition rails 410 arranged side by side, all of which are arranged at a certain interval along the second direction, and the first rail 100, the transition rail 410 and the second rail 200 correspond to each other in number and position.

[0041] It can be understood that the transition guide rail 410 can be hinged to the first guide rail 100 or the second guide rail 200, and the hinge axis of the transition guide rail 410 extends along the second direction, so that the transition guide rail 410 can rotate in the forward direction, so that the transition guide rail 410 can be connected to the first guide rail 100 and the second guide rail 200 respectively to cover the gap 600 between the first guide rail 100 and the second guide rail 200; and, the transition guide rail 410 can be rotated in the reverse direction, so that the transition guide rail 410 is separated from the first guide rail 100 and the second guide rail 200 respectively, so as to ensure that the second guide rail 200 can move smoothly in the second direction relative to the first guide rail 100, and avoid the movement of the second guide rail 200 being affected by the obstruction of the transition guide rail 410 and the first guide rail 100.

[0042] Of course, the transition rail 410 may also be installed on the ground so that the transition rail 410 can rotate relative to the first rail 100 and the second rail 200 , and the rotation axis of the transition rail 410 extends along the second direction.

[0043] The transition rail assembly is provided with a force bearing member 430, which is spaced apart from the transition rail assembly in the second direction. The force bearing member 430 may be cylindrical, square, triangular prism, etc.

[0044] It is understandable that the force-bearing member 430 is fixedly connected to the transition guide rail assembly, and the force-bearing member 430 is arranged on one side of the transition guide rail assembly in the second direction, so that the force-bearing member 430 can be arranged to avoid the kiln car body 300, so as to avoid the setting position of the force-bearing member 430 from hindering the movement of the kiln car body 300 on the transition guide rail assembly. The size and shape of the force-bearing member 430 can be set according to actual conditions, and are not specifically limited here. When the force-bearing member 430 is acted upon by an external force, the force-bearing member 430 will move downward, so that the force-bearing member 430 can drive the transition guide rail assembly to move, so that the transition guide rail assembly can rotate.

[0045] In some examples, each transition rail 410 is provided with a force-bearing member 430, and the force-bearing member 430 is located on either side of the transition rail 410 in the second direction. In other examples, a transmission rod is connected between all transition rails 410, and the transmission rod extends along the second direction, and one of the transition rails 410 is provided with a force-bearing member 430. When the force-bearing member 430 is subjected to an external force, the force-bearing member 430 drives the transition rail 410 fixedly connected thereto to rotate, and the transmission rod drives all transition rails 410 to rotate synchronously.

[0046] The transition guide rail assembly is configured to rotate forward when the force-bearing member 430 is subjected to external force, and overlap the second guide rail assembly, so that the first guide rail assembly, the transition guide rail assembly and the second guide rail assembly are connected in sequence to form a seamless guide rail assembly. Moreover, the transition guide rail assembly is configured to rotate in the opposite direction by itself after the external force is removed.

[0047] It can be understood that when the transition guide rail assembly is overlapped on the second guide rail assembly, the second guide rail assembly can provide sufficient support and limiting effect on the transition guide rail assembly, so that the transition guide rail assembly maintains a horizontal state, so that the first guide rail assembly, the transition guide rail assembly and the second guide rail assembly can be sequentially spliced ​​into a horizontal, seamless guide rail assembly. At this time, the upper surface of the first guide rail assembly, the upper surface of the transition guide rail assembly and the upper surface of the second guide rail assembly are flush and seamlessly connected, which can facilitate the movement of the kiln car main body 300 along the guide rail assembly and ensure that the kiln car main body 300 is stable and without shaking during the movement.

[0048] When the kiln car body 300 is completely transitioned to the second guide rail assembly, the external force acting on the force-bearing member 430 disappears. At this time, the transition guide rail assembly can be driven to rotate in the opposite direction by utilizing its own gravity, so that the transition guide rail assembly is separated from the first guide rail assembly and the second guide rail assembly, respectively. Specifically, one end of the transition guide rail assembly close to the second guide rail assembly is higher than the upper surface of the second guide rail assembly, and one end of the transition guide rail assembly close to the first guide rail assembly is lower than the upper surface of the first guide rail assembly.

[0049] Of course, the transition guide rail assembly can also use a torsion spring or a tension spring to rotate in the opposite direction to return the transition guide rail assembly to its initial state to complete the reset work.

[0050] The kiln car body 300 has wheels 310 at the bottom, and the wheels 310 can roll along the extension direction of the guide rail assembly. Specifically, there are four wheels 310, which are arranged in an array. The kiln car body 300 is provided with a force applying member 500, which is configured to apply an external force to the force receiving member 430 before the wheel 310 contacts the transition guide rail assembly.

[0051] It is understandable that the size and shape of the force-applying member 500 can be set according to actual needs, and no specific limitation is made here, as long as the force-applying member 500 can apply an external force to the force-receiving member 430. In some examples, a force-applying member 500 is provided at each wheel 310, and the force-applying member 500 and the wheel 310 are spaced apart in the second direction, so that the force-applying member 500 can avoid the wheel 310 and be arranged opposite to the force-receiving member 430 in the first direction. Then, before each wheel 310 is about to move onto the transition rail assembly, the force-applying member 500 can be used to apply an external force to the force-receiving member 430, so that the transition rail assembly can be connected with the first rail assembly and the second rail assembly respectively.

[0052] In other examples, a force-applying member 500 is provided for the two wheels 310 on the same side. When the first wheel 310 is ready to move to the transition guide rail assembly, the force-applying member 500 applies an external force to the force-bearing member 430 until the second wheel 310 completely passes the transition guide rail assembly. The force-bearing member 430 will continue to be pressed down by the force-applying member 500, so that the first guide rail assembly, the transition guide rail assembly and the second guide rail assembly remain in a horizontally connected state.

[0053] In the kiln car guide rail structure with seamless and efficient transition provided by the embodiment of the first aspect of the present invention, since a transition guide rail assembly with a force-bearing member 430 is added between the first guide rail assembly and the second guide rail assembly, and a force-applying member 500 is added to the kiln car main body 300, during the movement of the kiln car main body 300 from the first guide rail assembly to the second guide rail assembly, the force-applying member 500 applies an external force to the force-bearing member 430, so that the transition guide rail assembly rotates forwardly under the driving action of the force-bearing member 430 and rests on the second guide rail assembly, so that the transition guide rail assembly can make up for the gap 600 between the first guide rail assembly and the second guide rail assembly, so that the first guide rail assembly, the transition guide rail assembly and the second guide rail assembly are sequentially connected to form a seamless guide rail assembly, so that the kiln car main body 300 can move along the extension direction of the guide rail assembly, so that the kiln car main body 300 can be efficiently and stably transferred from the first guide rail assembly to the second guide rail assembly, thereby ensuring that the kiln car has high transportation safety for kiln tools and products 320.

[0054] When the kiln car body 300 is completely transferred to the second guide rail assembly, the external force applied by the force-applying member 500 to the force-receiving member 430 disappears, and the transition guide rail assembly automatically rotates in the opposite direction, so that the second guide rail assembly is separated from the transition guide rail assembly, making it easier for the second guide rail assembly to drive the kiln car body 300 to move relative to the first guide rail assembly along the second direction.

[0055] Through the above-mentioned unique structural design, when the kiln car main body 300 is about to move to the transition guide rail assembly, the transition guide rail assembly can be driven to rotate and overlap on the second guide rail assembly through the cooperation of the force applying member 500 and the force receiving member 430, so that the first guide rail assembly, the second guide rail assembly and the transition guide rail assembly together constitute a guide rail assembly, and there is no need to additionally set up a detection device for detecting the position of the kiln car main body 300 and a driving device for driving the transition guide rail assembly to actively rotate, thereby reducing energy consumption, saving manufacturing costs, and shortening the transition time consumed by the kiln car main body 300, so that the kiln car main body 300 can be efficiently and stably moved from the first guide rail assembly to the second guide rail assembly.

[0056] In some embodiments, Figure 1 , Figure 3 and Figure 6 As shown, each first guide rail 100 is provided with a first support portion, each second guide rail 200 is provided with a second support portion, and the transition guide rail 410 is configured to abut against the upper surface of the first support portion and the upper surface of the second support portion when the first guide rail 100, the transition guide rail 410 and the second guide rail 200 are sequentially connected to form a guide rail assembly.

[0057] It is understandable that the shapes of the first support portion and the second support portion can be set according to the shape of the transition rail 410, and are not specifically limited here, as long as the first support portion and the second support portion can provide sufficient support to the transition rail 410. By setting it in this way, the first rail 100 and the second rail 200 share the force borne by the transition rail 410, so that the transition rail 410 can maintain a horizontal state, and the transition rail 410 and the second rail 200 are prevented from being easily deformed due to excessive force.

[0058] In a specific embodiment, each first guide rail 100 is provided with a first notch 110 on one side in the second direction, and each second guide rail 200 is provided with a second notch 210 on one side in the second direction, and the first notch 110 and the second notch 210 are arranged opposite to each other in the first direction. The first notch 110 and the second notch 210 are both opened upward, and in order to facilitate the installation of the transition guide rail 410, the first notch 110 penetrates a side surface of the first guide rail 100 in the second direction, and the second notch 210 penetrates a side surface of the second guide rail 200 in the second direction. The first notch 110 and the second notch 210 can allow the transition guide rail 410 to rotate forward and reverse. The first support portion is located in the first notch 110, and the second support portion is located in the second notch 210.

[0059] It is understandable that the shapes of the first notch 110 and the second notch 210 can be set according to actual needs and are not specifically limited here. When the transition guide rail 410 rotates forward and rotates to a horizontal state, the lower surface of the transition guide rail 410 is supported by the first guide rail 100 and the second guide rail 200. When the transition guide rail 410 rotates reversely, the transition guide rail 410 will separate from the first support portion and the second support portion. Specifically, the end of the transition guide rail 410 close to the second guide rail 200 will swing upward and disengage from the second notch 210.

[0060] Of course, it is not excluded that in other embodiments, the second guide rail 200 is provided with the second supporting portion, while the first guide rail 100 is not provided with the first supporting portion.

[0061] In some embodiments, Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the transition rail 410 is arranged on the first rail 100, and the transition rail 410 and the first rail 100 are connected through the first hinge shaft 440, so that the transition rail 410 can rotate forward or reversely relative to the first rail 100 around the first hinge shaft 440. Moreover, the length of the first hinge shaft 440 extends along the second direction, and the first hinge shaft 440 is located on the side of the first notch 110 away from the second rail 200. The first hinge shaft 440 can be a pin with a thread, and the first rail 100 is correspondingly provided with a threaded hole so as to be threadedly connected with the first hinge shaft 440, so that the first hinge shaft 440 is fixed relative to the first rail 100, and the transition rail 410 is provided with a hinge hole so that the first hinge shaft 440 passes through.

[0062] In addition, the transition guide assembly also includes a return spring 420. The return spring 420 is connected to the transition guide 410 and the first guide 100, respectively, and the return spring 420 is configured to drive the transition guide 410 to rotate in the opposite direction around the first hinge shaft 440. It is understandable that the return spring 420 can be a torsion spring or a tension spring. When the force-applying member 500 applies an external force to the force-bearing member 430, the force-bearing member 430 will drive the transition guide 410 to rotate in the forward direction. At this time, the transition guide 410 will apply a force to the return spring 420, causing the return spring 420 to deform and generate elastic potential energy. When the external force is removed, the return spring 420 uses the elastic potential energy of the return spring 420 to drive the transition guide 410 to rotate in the opposite direction.

[0063] In a specific embodiment, the return spring 420 is a tension spring, which is located below the first hinge shaft 440, one end of which is fixedly connected to the first guide rail 100, and the other end of which is fixedly connected to an end of the transition guide rail 410 away from the second guide rail 200. The length direction of the tension spring can extend in the up-down direction, such as Figure 6 The force bearing member 430 is located on the side of the first hinge shaft 440 close to the second guide rail 200, and the tension spring is located on the side of the first hinge shaft 440 close to the first guide rail 100. When the force bearing member 430 is not acted upon by an external force, the transition guide rail 410 maintains an inclined state under the tension of the tension spring, and at this time, the end of the transition guide rail 410 close to the first guide rail 100 is lower than the upper surface of the first guide rail 100, and the end of the transition guide rail 410 close to the second guide rail 200 is higher than the upper surface of the second guide rail 200.

[0064] In some embodiments, the width of the transition rail 410 in the second direction is greater than or equal to half of the width of the first rail 100 in the second direction, and the first rail 100 and the second rail 200 are arranged with equal width. Figure 4As shown, the width direction of the first guide rail 100 , the width direction of the second guide rail 200 , and the width direction of the transition guide rail 410 all extend along the second direction, the width of the first guide rail 100 is equal to the width of the second guide rail 200 , and the width of the transition guide rail 410 is equal to half of the width of the first guide rail 100 .

[0065] By such arrangement, when the kiln car main body 300 passes through the gap 600 between the first guide rail 100 and the second guide rail 200, the contact area between the transition guide rail 410 and the wheel 310 of the kiln car main body 300 can be increased, and the pressure of the wheel 310 on the transition guide rail 410 can be reduced, thereby preventing the transition guide rail 410 from being easily deformed, and ensuring that the kiln car main body 300 can move smoothly.

[0066] Of course, in other embodiments, the width dimension of the transition rail 410 is equal to the width dimension of the first rail 100 .

[0067] In a specific embodiment, Figures 1 to 4 , Figure 6 As shown, the force bearing member 430 is a pressure wheel, which is connected to the transition rail 410 via a second hinge shaft, so that the pressure wheel can rotate relative to the transition rail 410 around the second hinge shaft. Moreover, the length of the second hinge shaft extends along the second direction, and the pressure wheel is higher than the upper surface of the first rail 100.

[0068] With such a design, when the wheel 310 of the kiln car body 300 is about to move to the transition guide rail 410, the force-applying member 500 can contact the outer peripheral surface of the pressure wheel and apply a certain force to the pressure wheel, so that the pressure wheel drives the transition guide rail 410 to swing downward around the first hinge shaft 440. In the process of the wheel 310 passing through the transition guide rail 410, the lower surface of the force-applying member 500 is a horizontal plane and will maintain an abutment state with the outer peripheral surface of the pressure wheel, so that the transition guide rail 410 is horizontally connected with the first guide rail 100 and the second guide rail 200. At this time, the pressure wheel will rotate, reducing the friction between the pressure wheel and the force-applying member 500, avoiding the force-bearing member 430 and the force-applying member 500 from wearing too quickly, thereby extending the service life of the force-bearing member 430 and the force-applying member 500.

[0069] Furthermore, the force applying member 500 is provided with a guide surface 510, which can be a guide plane or a guide arc surface. The guide surface 510 can contact the pressure wheel and drive the pressure wheel to drive the transition guide rail 410 to rotate in the positive direction. In this embodiment, the guide surface 510 is a guide plane, which is arranged obliquely upward from the first guide rail 100 to the second guide rail 200.

[0070] It is understandable that when the force-applying member 500 is about to contact the pressure wheel, the guide surface 510 can guide the pressure wheel, so that the pressure wheel can move along the guide surface 510 and move to the lower surface of the force-applying member 500. Since the force-applying member 500 is fixed relative to the kiln car body 300, during the horizontal movement of the kiln car body 300, the force-applying member 500 will exert a downward pressure on the pressure wheel, so that the pressure wheel will move downward relative to the force-applying member 500, so that the pressure wheel can drive the transition guide 410 to rotate downward.

[0071] Of course, it is not excluded that in other embodiments, the force-bearing member 430 is fixedly connected to the transition guide rail 410 , the force-bearing member 430 is provided with a guiding slope or a guiding arc surface, and the force-applying member 500 may be provided with a guiding surface 510 or not.

[0072] In some embodiments, Figure 1 and Figure 5 As shown, each wheel 310 is provided with a force-applying member 500 on one side in the second direction, and the force-applying member 500 is provided with guide surfaces 510 at both opposite ends in the first direction. In this embodiment, the force-applying member 500 is in an isosceles trapezoidal shape when viewed along the second direction. For two wheels 310 in the second direction, the two force-applying members 500 are symmetrically arranged in the second direction. Moreover, for the same force-applying member 500, the spacing between the two guide surfaces 510 in the first direction is greater than the outer diameter of the wheel 310.

[0073] It is understandable that such a design enables the kiln car body 300 to efficiently and smoothly transition from the first guide rail assembly to the second guide rail assembly, and also to efficiently and smoothly transition from the second guide rail assembly to the first guide rail assembly. Specifically, the first guide rail assembly is located on the left side of the second guide rail assembly. When the kiln car body 300 moves from left to right, each wheel 310 applies an external force to the force receiving member 430 through the force applying member 500, so that the wheel 310 passes through the first guide rail 100, the transition guide rail 410 and the second guide rail 200 in sequence. When the kiln car body 300 moves from right to left, each wheel 310 can still use the force applying member 500 to apply an external force to the force receiving member 430, so that the wheel 310 can pass through the second guide rail 200, the transition guide rail 410 and the second guide rail 200 in sequence.

[0074] When each wheel 310 completely passes through the transition guide rail 410 , the transition guide rail 410 will automatically reset under the action of the reset spring 420 .

[0075] like Figures 1 to 7 As shown, the kiln according to the second embodiment of the present invention includes a kiln car guide rail structure with seamless and efficient transition as in the first embodiment.

[0076] The kiln not only includes a tunnel kiln body, but also includes a translation vehicle 700. The second guide rail assembly is arranged on the translation vehicle 700, and the translation vehicle 700 is configured to be movable along the second direction.

[0077] Specifically, a first guide rail assembly is provided inside the tunnel kiln body, and the first guide rail assembly can extend along the extension direction of the tunnel kiln body, so that the kiln car body 300 moves along the first guide rail assembly, and the kiln car body 300 moves from the kiln head to the kiln tail of the tunnel kiln body. In addition, a first guide rail assembly is also provided outside the tunnel kiln body, and the first guide rail assembly is used as a return line and is arranged side by side with the first guide rail assembly inside the tunnel kiln body, such as Figure 7 shown. Figure 7 The arrow direction in refractory 1 indicates the moving direction of the kiln car main body 300 .

[0078] Transition rail assemblies are provided at opposite ends of the first rail assembly located inside and outside the tunnel kiln body. In addition, a translation vehicle 700 is provided at opposite sides of the tunnel kiln body in the first direction. The translation vehicle 700 is provided at a tunnel 810. Two translation rails 820 arranged side by side along the first direction are provided in the tunnel 810. The length of the translation rails 820 extends along the second direction. The translation vehicle 700 can move along the extension direction of the translation rails 820. Therefore, through the cooperation of the translation vehicle 700, the second rail assembly and the first rail assembly located inside and outside the tunnel kiln body, the kiln car body 300 can move from the kiln head of the tunnel kiln body to the kiln tail, and translate from the kiln tail to the return line, and finally translate from the return line to the kiln head, so that the kiln car body 300 can move along the circulation path and complete the firing and unloading of the product 320.

[0079] It is understandable that if Figure 5 and Figure 6 As shown, the translation vehicle 700 is an existing structure. Four running wheels 750 are provided at the bottom of the translation vehicle 700. The running wheels 750 are driven by a second chain drive device. After the second motor 740 in the second chain drive device is started, the running wheels 750 can roll on the translation guide rail 820. The translation vehicle 700 is provided with locking rods 760 on opposite sides in the first direction. The locking rods 760 can be driven by a hydraulic drive device so that the locking rods 760 can be extended and retracted in the first direction. When the locking rods 760 are extended and connected to the locking assembly in the tunnel 810, the translation vehicle 700 is fixed relative to the tunnel 810 in the second direction.

[0080] Moreover, a translation seat 720 is provided at the middle position of the translation vehicle 700 in the second direction. The translation seat 720 is driven by a first chain driving device. When the first motor 730 in the first chain driving device is running, the translation seat 720 can move relative to the translation vehicle 700 in the first direction. Two barbs 710 are provided on the translation seat 720. The barbs 710 can be driven to rotate by a cylinder. The barbs 710 are used to hook the kiln car body 300. When the translation seat 720 moves with the barbs 710 in the first direction to the bottom of the kiln car body 300 located on the first guide rail assembly, the barbs 710 can be used to hook the kiln car body 300. Then, the translation seat 720 drives the barbs 710 to move in the opposite direction in the first direction, so that the kiln car body 300 is smoothly transferred from the first guide rail assembly to the second guide rail assembly on the translation vehicle 700 under the driving action of the barbs 710.

[0081] The use process of the kiln in this embodiment is as follows: the kiln car body 300 carries the product body along the first guide rail assembly into the tunnel kiln body. After the product body is roasted, the kiln car body 300 moves forward with the product 320 in the direction of the translation vehicle 700 under the propulsion of the stepper motor and arrives at the tail of the kiln. At this time, the first guide rail assembly and the second guide rail assembly on the translation vehicle 700 are arranged relative to each other.

[0082] Next, the first motor 730 on the translation vehicle 700 is started, and drives the translation seat 720 to move with the barb 710 toward the kiln car body 300. After the barb 710 is snap-connected with the kiln car body 300, the output shaft of the first motor 730 rotates in the opposite direction, so that the barb 710 on the translation seat 720 drives the kiln car body 300 to move toward the translation vehicle 700. During the movement of the kiln car body 300, the force-applying member 500 on the kiln car body 300 applies an external force to the force-bearing member 430 on the transition guide rail assembly, so that the transition guide rail assembly is horizontally connected with the first guide rail assembly and the second guide rail assembly respectively and forms a seamless guide rail assembly, so that the wheel 310 of the kiln car body 300 rolls along the guide rail assembly, so that the kiln car body 300 moves to the translation vehicle 700.

[0083] When the kiln car body 300 is completely transferred to the second guide rail assembly on the translation car 700, the car locking rod 760 on the translation car 700 is retracted, and the second motor 740 is operated to drive the translation car 700 to drive the kiln car body 300 to move along the translation guide rail 820, so as to achieve the translation of the kiln car body 300 in the second direction, so as to transfer the kiln car body 300 from the tunnel kiln body to the return line.

[0084] When the trolley 700 moves to the position along the second direction, the locking rod 760 on the trolley 700 extends and hits the locking assembly in the tunnel 810, so that the trolley 700 is fixed relative to the tunnel 810. At this time, the second guide rail assembly on the trolley 700 is aligned with the first guide rail assembly on the return line. Subsequently, the first motor 730 is activated to allow the translation seat 720 to drive the kiln car body 300 to move along the first direction through the barb 710. Through the cooperation of the force applying member 500 and the force receiving member 430, the kiln car body 300 can be stably transferred from the trolley 700 to the return line, so as to unload the products 320 on the kiln car body 300 on the return line.

[0085] Similarly, the kiln car body 300 can smoothly transition from the return line to the translation car 700 located at the kiln head, and can be smoothly and stably transferred from the translation car 700 to the kiln head.

[0086] The kiln provided in the second aspect of the present invention adopts the above-mentioned seamless and efficient transition kiln car guide rail structure, which can realize the smooth and efficient circulation movement of the kiln car body 300 and safely transport the kiln tools and fired products 320.
